You've let a house plant die through neglect before. Probably not even just the once. Multiple times over. You are a bad house plant parent, but things could change around if you had one of these.

| My micro:bit water sensor showing animated "don't water me". |
The micro:bit water sensor connects to your micro:bit through the pins provided at the bottom of your device. Black to ground; red to 3V and the blue to whichever pin (0-2) you wish to read.
My first project is a simple soil-moisture detector for a houseplant. When the moisture level is okay for the plant then the micro:bit displays an animated cross ("do not water"); when the soil is dry then the micro:bit displays animated drops of rain ("water me").
Very simple.
Feel free to get my code.

| Here I am continually reading the analog pin (P2) and storing the value in a variable called 'water'. I found that a value less than 10 means 'bone dry'. |

The water sensor is a fun addition to the micro:bit computer and there are clearly multiple fun projects to attempt. You can get your water sensor here.
